Cooling towers are notoriously difficult applications for chlorine and bromine sensors.
Many operate at high cycles of concentrations (very high conductivity and hardness) and often use film forming corrosion inhibitors and have organic contaminants. HSI's sensor is ideally suited for these challenging applications. It can measure either chlorine or bromine and its self-cleaning features clean the electrodes continuously. Its built-in conductivity sensor can eliminate several discrete sensors.
